ADJUSTABLE SUPPORT FOR VAPOR-LAMPS.

To all whom it nmy concern:

Be it known that I, STANWOOD E. FLIGHT- NER, a citizen of the United States, and a resident of Englewood, county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Adjustable Supports for V apor-Lamps, of which the fol lowing 1s a specification. I

The present lnventlon relates to frames for-vapor electric lamps. such as are representednby the well-known mercury-vapor lamps now in common use.

The special object of the invention is to provide means whereby the starting of such lamps may be readily accomplished either singly or in groups by means of tilting apparatus in which connection is first made be tween the negative and positive electrodes through a stream or column of mercury, and afterward such connection is broken by a proper manipulation of the apparatus, so that the current which originally flowed through the va or column or stream shall pass through t e vapor-path between the main positive and the main negative electrodes.

It has been found in practice that a variety of tilting frames is requiredfor various purposes, whether for photographing by means of mercury-vapor lamps-or for printing, ens larging, or copying, as the case may be.

e drawing represents'a side elevation of one embodiment of. my invention, the. same consisting of an apparatus for so-called con tinuous blue-printing, I

In the drawings the rinting-frame 38 is hinged at 46 to the base liy standard 39.

At 47 isindicated. a shelf, which is also hinged to the base or standard 39, supporting Specification of Letters Patent. Application filed July 28. 1904. Serial No. 218,473.

The lamp operating the other end of the frame 38.

adapted is shown in its normal condition. To start the lamp by end of' the frame is lifted to the the mercury forms a connection between the two electrodes. into the dotted-line position, permitting the frame to drop into the position shown by the lower dotted lines, thus allowing the mercury torflow back to. its proper position. The frame 38 is then raised, the shelf 47 is returned to its place, and the frame is dropped upon the said shelf and supported in a orizontal position.

I claim as my invent-ion 1. In a printing apparatus, vapor electriclighting apparatus mounted upon a plate, a hinge at one end of said plate, a hinged support at the opposite end thereof, and means whereby the said plate can be moved to an inclined position either above or below its normal operating position.

2. In a lighting apparatus mounted on a suitable late,ahinge at one end of the said plate, a inged support at the opposite end of the said plate, means whereby the plate may be moved to an upwardly-inclined position, and means whereby the support may be withdrawn for moving the plate to a downwardlyinclined position.
